Path of the Storm Herald

Typical barbarians harbor a fury that dwells within. Their rage grants them superior strength, durability, and speed. Barbarians who follow the Path of the Storm Herald learn instead to transform their rage into a mantle of primal magic that swirls around them. When in a fury, a barbarian of this path taps into nature to create powerful, magical effects.

Storm heralds are typically elite champions who train alongside druids, rangers, and others sworn to protect the natural realm. Storm heralds are most common among the Eldeen Reaches and Shadow Marches. Other storm heralds hone their craft in elite lodges founded in regions wracked by storms typical in Xen’drik, in the frozen reaches of the world’s end like the Frostfell, or deep in the most blistering deserts such as Menechtarun, the Blade Desert and the Demon Wastes.

Storm of Fury

When you select this path at 3rd level, choose one to attune to one the following options: desert, forest, khyber, mountain, plains, sea, or tundra. The environment you choose shapes the nature of the storm you conjure when you rage.

You can choose another environment option at 7th level and 13th level. During a long rest you are able to attune to the land around you and change the effect of the aura of your Storm Fury to another option you have chosen. If you have chosen an option that matches the environment you are currently in, you must attune to that option. For example, by 7th level you have chosen to be able to attune to forest and mountain. If you find yourself in the mountain, you must attune to your mountain option. If you find yourself in khyber, you can attune to either forest or mountain.

While raging, you emanate an aura in a 5 foot radius. The effects of this aura depend on your chosen environment.
